class ListBuilder extends Dynamic {
  private var res = List[String]()

  def applyDynamic(method: String)(args: Any*) = {
    val argString = if (args.length>0) "(" + args.mkString(" ") + ")" else ""
    res = method + argString :: res
    this
  }
  
  def result = res.reverse
}

val lb = new ListBuilder
lb.any.method("with", 100, "parameters").you.like
println(lb.result) // List(any, method(with 100 parameters), you, like)
